ffmpeg -- and other multimedia tools -- is available through the rpmfusion repository. Instructions for configuring your system to use rpmfusion are available here.

How to switch back the repository afterwards? – flv Dec 13 '10 at 14:39
You don't need to "switch back" the repository. Your system can use multiple repositories. If you don't want it enabled by default, you can set "enabled=0" in the repository configuration and then use it explicitly with something like "yum --enablerepo=rpmfusion" on the command line. – larsks Dec 13 '10 at 14:46
